DRIVING ATTACHMENT FOR CREAM-SEPARATORS Specification of Letters Patent.

Patented May 2, '1911.

Application filed April 26, 1909. Serial No. 492,262.

To all whom 'it may concern:

Be it known that I, OTTO F. KoHLwEr, a citizen of the United States,residing at Grafton, county of ()zaukee, and State of Wisconsin, haveinvented new and useful 'Improvei'i'ients in Driving Attachments forCream-Scparators, of which the following is a specification.

My invention relates to improvements in driving connections for creamseparators of that class in which the bowl supporting spindle issuspended from the upper end. Such spindles are ordinarily drivenmanually through crank and gearing connections, and the object of myinvention is to provide means whereby such connections may be usedinterchangeably with driving connections actuated by mechanical power.

In the following description, reference is had to the accompanyingdrawing, in which the figure is a vertical sectional view, drawn on theaxis of, the spindle and longitudi' nally of the gear casing, showing mymproved power driving connections applied thereto, and with dotted linesindicating the position of some of the manually actuated gearing, whichis removed when the spindle is driven by mechanical power.

1 is the bowl casing and 2 the gear casing of the separator.

3 is the supply pipe, 4 the separating bowl and 5 the bowl supportingspindle, sus pended by a head 6 upon ball bearings 7. The head 6 issecured to the end of the spindle by a screw 8, having the ordinarycross groove .01" channel, and when driven manually, the power isapplied to the spindle .throu h a pinion at 9 and manually actuatedgears coated in the casing 2, p a When. it is desired to drive theseparator by mechanical power, the cap of the gear casing 2 is removedand a cap l1 substituted, which is dpro vided with an upwardly extendingstan ard 13, supportin a vertically disosed auxiliary drivin siaft 15 inbearngs at 16 and 17. This shaft 15 is flattened and tapered at itslower end, the form being similar to that of a screw driver,

adapted to engage the head of the screw 8. A bushing 19 is fitted to,butloose on the shaft and at its lower end, and is adapted to looselyfit over the head of the screw, when the shaft supporting attachment isin with driving connections,

operative position. This'bushing holds the auxiliary shaft in alinementwith the spindle. A driving pulley 21 is fast on the shaft and isactuated by a belt or chain 23. The separator can thus be driven bymechanical power and substitution of such power for manual power can bemade without disarranging any of the working parts of the separator orinterfering with the free runnin movement secured in such separaters ysuspending the spindle from its upper end. The bearing Q-l in the lowerportion of the casing is a loose guide bearportion of the casing isa-looso guide bearing.

Having thus described my invention, what I claim new, and desire tosecure by Letters Patent, is

1.,In a cream separator, the combination of a suspended bowl supportingseparator spindle provided with a transverse groove at its upper end, ofa gear casing, removable ge-aring therein for actuating said spindle, aremovable cap for said casing, provided with a bearing standard, and anauxiliary shaft 'journaled in said standard and provided with drivingconnections exterior to saidcasing, said auxiliary shaft bein flattenedand tapered at its lower end and adapted to engage in said transversegroove, whereby said spindle may be driven either by means of theinterior removable gearing, or by the exterior auxiliary shaft.

2. In a cream sepa ator, the combination of a suspended bowl supportingseparator spindle provided with a transverse groove at its upper end, ofa gear casing, removable driving connect-ions therein, a removable capfor the casing, provided with a bearing standard, and an auxiliary shaftjournaled in 'said standard and provided said auxiliary shaft beingflattened and tapered at its lower end and adapted to en age in saidtransverse groove, together wit a bushin loosely fitted to the auxiliaryshaft an covering the tapered portion, with its lower end looselyengaging the end of the spindle. In testimony whereof I attix mysignature in the utesence of two witnesses. OTTO l KO'IILWEY.
